Question

There are 63 new houses being built in a neighborhood. last month 1/3 of them were sold. this month 2/7 of the remaining houses were sold. How many houses are left to be sold?

Answer 1

Answer: 49 houses

Explanation:

63 x 1/3 =63/3= 21 houses were sold last month. 63 - 21 = 42 houses remained unsold last month. 42 x 2/3 =[42 x 2] / 3 = 84 / 3 = 28 houses were sold this month. 21 + 28 = 49 houses sold altogether.
